I've got a broken rail on my bolt sled:

The gap isn't actually that wide; in the picture, I'm holding it open a little bit for visibility.

Is there a good way to patch this up so that it will have reliable integrity again? There doesn't seem to be room to glue even a thin patch onto it, and it seems like gluing the break itself wouldn't carry weight for very long before it broke open again. Any ideas, or do I need to buy another LS just for the damn bolt sled?

Fun fact: before I figured out that the sled was broken, it was behaving as though I needed a stronger spring on the trigger plate / plunger catch. I'd try to prime it, and it would rarely click. I guess I'm a dipshit for not noticing, but if you replace the trigger plate spring and the problem persists, that's something to look at. For future reference.

I was wondering if anybody had experimented with getting their brass barrel rifled by a gunsmith, and whether it helped or hindered the gun's performance.

Would the grooves introduce a small amount of friction and diminish the overall range?

Would the grooves allow some air to pass around the dart, decreasing the pressure on it and making it fall to the ground a flacid ten feet away?

Would they improve accuracy at all? I can see stefans being able to fly straigt and true on their own, but maybe a stock dart would fly better if it had a spin to it.

Has anybody tried this? Is there an obvious property of Nerf physics that makes this obviously foolish?

I was getting ready to unscrew my LS and take it apart when I realized that the bolt primer (my terminology may be wrong; the two orange pegs connected by a metal rod) doesn't seem interested in coming off. Is there a way to get that off without breaking something, or am I a chump for attaching the piece as soon as I pulled the gun out of the box?

I haven't tried anything so aggressive as trying to rip it off with a pair of pliers. I figured that there must be a painless way to remove it since I can't find mention of this problem anywhere.
